Duet3D Filament Monitor - Multiple Types - V3.0

Born of a collaboration between Duet3D and E3D, this filament monitor very accurately senses filament movement. Connect it to a Duet 2 or Duet 3 and the controller will use the indicated movement to determine a wide range of extrusion issues including:

• Filament run out
• Extruder skipping steps
• Nozzle starting to jam (causing skipped steps or grinding)
• Filament beginning to grind in the extruder

It does this so accurately because it is effectively an extruder in reverse. The filament movement rotates a custom machined hobbed magnet assembly; the magnet rotation is sensed and constantly reported to the Duet. This method has proven extremely accurate across a wide range of filaments – frequently capable of pausing the print before a filament jam or other issue has already caused the print to fail.

Options:

Kit: The monitor is available as a kit excluding the printed housing (we provide a design).

Assembled: Fully assembled in a MJF printed housing. 

Both versions include a connector pack with the Molex-KK-style housings and crimps to connect the monitor to the Duet board.
